Claims.

This invention relates to a metal seaming tool, the general object ofthe invention being to so form and construct the tool that the one toolcan be used in forming the single seam and then by slight adjustmentlthe tool can be used for forming a double seam, the device being mainlyintended for forming seams in roong metals.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts to behereinafter fully described, illustra-ted in the accompanying drawingsand specically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is an elevational view of the tool.

Figure 2 is an edge view thereof.

Figure 3 is a fragmentary edge view showing the attachment in operativeposition.

Figure 4 is a similar view showing the attachment in inoperativeposition.

Figure 5 is a section on the line 5-5 of Figure 1.

Figure 6 is a section on the line 6-B of Figure 2..

Figure 7 is a sectional view of the jaws showing the initial step offorming a single seam, and

Figure 8 is a similar view showing the jaws in position for forming adouble seam.

In these views the numeral I indicates one of the handle members whichis formed with an elongated forked part 2 and an elongated transverselyextending jaw part 3 has its central portion connected with the lowerend of the prongs of this forked part. This jaw part 3 has an arcuateouter edge with its inner edge of stepped formation as shown at 3'. Arelatively short shank 4 is located between the prongs of .the forkedpart and has its lower end curving away from the reduced lower end ofthe forked part and a pivot bolt 5 extends through the lower portions ofthe prongs of the forked part and through the lower part of the shankand plvotally connecting the shank with the forked part. A jaw formingpart 1 of elongated form extends transversely of the shank and has itscentral portion connected with the curved part 6 of the shank and thisjaw part 1 is of substantially angle shape in cross section to provide apart for fitting in the recess formed by the stepped part 3 of the jawpart 3 and a depending part for tting against the inner side edge of thelower portion of the jaw part 3. This depending part of the jaw part 1is formed with -a V-shaped groove 8 at its lower edge. The upper end ofthe shank is provided with a segmental gear 9 and a handle part I0 isformed with a segmental gear I I at its lower end for engaging thegear9, a pivot bolt I2 passing through the prongs of the par-t 2 and throughthe lower enlarged end of the handle part Ill for pivotally connectingthe handle part I0 to the forked part with the two gears meshing witheachother. The handle part I curves outwardly and upwardly fromtheforked part 2 and this part I and the part I0 have fiat upper endsI3.

Thus by moving the handle part I the segmental gears Will turn the shank4 on its pivot 5 to cause the jaw part 1 to engage the jaw part 3 or togrip the metal between the two jaw parts,

An elongated channel member I4 has one of its flanges longer than theother and the long flange is provided with a longitudinally extendingslot I5 while the short flange is provided with a tapered hole I6. ofthe jaw part 1 and a bolt I1 passes through one end of the jaw part 1and through the tapered hole I6 of the short flange of the member I4. Abolt I8 extends from the opposite end of the jaw part 1 and passesthrough the slot I5 in the long ange of the member I4 and receives awing nut I9. The inner edge of the member I4 is formed with a V-shapedrib 20 for engaging the groove 8 in the depending part of the jaw member1 as more clearly shown in Figure 5. By loosening the nut I-9 andpushing the long flange of the member I4 downwardly the rib of themember I4 can be released from the jaw 1, the tapered opening I 6through which the bolt I1 passes permitting this downward movement ofthe member I4. Then the member I4 can be swung upwardly to the positionshown in Figure 4 after which the thumb nut is tightened to hold themember I4 in this position.

When the device is used for forming a single seam in a pair of roofingsheets, for instance, the member I4 is moved to the position shown inFigures 1. ,2, 3, 5 and 6 and then the edges of the two sheets aregripped between the jaw members by moving the handle member I0 away fromthe handle part I and then the tool is manipulated to make the'singleseam. Then when the double seam is to be made, following the formationof the single seam, the member I4 is moved to an inoperative position,shown in Figure 4, which shortens the height of the jaw 1 and the toolis then used on the single seam in the same manner to form the singleseam into a double seam.

It is thought from the foregoing description The fianges engage the endsthat the advantages and novel features of the invention will be readilyapparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts provided thatsuch changes fall within the scope of the appended claims.

Having described the invention, what is claimed as new is:
